Emergency center (ER) trauma evaluations often include leukocyte count (LC), serum amylase (SA), electrolytes (EL), and urine analysis. We reviewed records of 100 pediatric ER patients to determine utility of these tests in management of blunt injury. SA was evaluated in 65 patients and ranged from 30-146 U/L (mean 50.6 U/L); 14 patients with normal CT scans had SA from 30-68 U/L (mean 49.1 U/L). ⋯ DA predicted injury with sensitivity 60.0 per cent (specificity 79.2%). DA accurately represented LA results (sensitivity 100%, specificity of 94.5%). DA is a rapid and effective replacement of LA in evaluation of trauma patients in the emergency center.

Comparative StudySurvival after hypertonic saline resuscitation from hemorrhage.
There has been recent increased interest in hypertonic saline resuscitation from shock and hemorrhage. This study was performed to evaluate the survival effects of hypertonic saline resuscitation. Fifty male Sprague-Dawley rats of average weight of 325 grams were anesthetized with halothane. ⋯ Rats were observed 3 days for survival. Survival was significantly lower in the three per cent NaCl group compared with the lactated Ringer's group. It is probable that worsened outcome with three per cent NaCl was associated with intracellular dehydration.

Three cases of postoperative pulmonary lobe torsion were reported. Two of three showed hemorrhagic infarctions, and as a result underwent rethoracotomies and removal of the affected lobes. From these experiences, we consider that computed tomography (CT) and bronchofiberscopic examinations are useful for the diagnosis of advanced torsion.

The charts of 56 consecutive patients with penetrating injuries to the abdominal aorta were reviewed in an attempt to identify prognostic factors. Mechanism of injury was gunshot wound (GSW), 82 per cent (.22 cal: 15.2%; greater than .38 cal: 84.8%); shotgun wound (SGW), 5 per cent; and stab wound (SW), 13 per cent. Overall mortality was 73 per cent, with GSW 78 per cent (.22 cal: 0%; greater than .38 cal: 92%), 67 per cent with SGW, and 43 per cent with SW. ⋯ At surgery, six patients had thoracotomy before celiotomy for control of the thoracic aorta, with three surviving the OR and two surviving long-term. Survivors had 2.53 associated injuries; nonsurvivors had 2.89 (NS). No significant difference was noted in number or location of associated injuries between survivors and nonsurvivors.(ABSTRACT TRUNCATED AT 250 WORDS)

Case ReportsSurvival after blunt traumatic rupture of the left ventricle.
There have been 11 reported survivors from blunt-trauma-induced right ventricular rupture and only three from left ventricular rupture. We report the fourth case of a survivor of blunt left ventricular rupture. This patient presented with hypotension from both hemorrhage into the left chest and pericardial tamponade. The tamponade was relieved via an emergent left thoracotomy, the bleeding from the rent in the left ventricle was easily controlled, and repair was straightforward.
